There are thousands of ways of earning money online, but be careful 30-40% of them are scams.
the best way of erning money online should be by clicking ads.
I am a member of online company, which pays its members like me to view ads. SIMPLE AS 1,2,3!!!!
For example, there is a website lets call it X, this website doesn't get enough traffic and it offers something like "Make money online" (but you will still have to pay for websites like that), so website X goes to a another company lets call it Y, and website X asks website Y to get people on their website and X pays Y money to get people there. So I am a member of website Y, they pay me to go to websites that X offers.
The website Y is: http://hits4pay.com/cgi-bin/redirect.cgi
They also pay you $10 for only a signup!!!!!!!!!!!
